The lighter on the bottom (e.g. Navy jacket with white trousers) look, to me, comes off as "feminine" rather than "masculine."
It's not a "RULE" but my own personal color pyramid preference, I guess. Men to me look better with the traditional pyramid, while women can do whatever they want with the thing.
Style versus fashion?- M

Not something that stark. I mean like a brown gunclub sportcoat with mid grey trousers.

Have to disagree, M. I'm actually wearing navy pants and a tan barleycorn SC right now. This morning I really wanted to like it, but I don't think it looks as natural as a pair of khakis or mid grey trou and navy SC/blazer.

It was definitely an experiment. I think it looks decent, though I don't think I'll try to replicate the look again. I like the way that the textures combine, even if the colors are less than ideal. Pretty sure I woke up drunk, so that's likely why I was feeling daring.
